Abstract
A method of making a hollow ornamental knotted article includes: forming a thread into a loose knotting which confines a hollow space; wrapping a solvent-soluble filler with a protective material, and inserting the wrapped filler into the hollow space; tightening the thread so as to tie tightly the wrapped filler and adjust the loose knotting into a tight knotting; applying a shape-setting liquid to the tight knotting so as to set the profile of the tight knotting; and injecting a solvent into the filler through the protective material to dissolve the filler, and drawing out the dissolved filler and the protective material from the hollow space, thus forming a hollow ornamental knotting.
